Embodiment Construction

[0014] The embodiment of the system for identifying vehicles merging across a solid line at a traffic intersection according to the present invention will be described in detail below with reference to the accompanying drawings.

[0015] Before the vehicles at the current traffic intersection wait for the cut-off line, in order to prevent traffic chaos or even major accidents caused by vehicles switching back and forth in each traffic channel, the road traffic management department generally sets a solid line area, which is a The rectangular area is composed of four straight lines on the periphery. According to the number of traffic channels inside the rectangular area, multiple sub-rectangular areas are divided in the direction perpendicular to the vehicle waiting cut-off line. Each sub-rectangular area corresponds to a traffic channel. The traffic channel may include left Turn channel, right turn channel, straight channel and U-turn channel, etc.

[0016] Before the vehicle ...

Abstract

The invention relates to a system for recognizing a vehicle crossing a full line and changing lanes at a traffic intersection. The system comprises a mobile hard disk, an AT89C51 single chip microcomputer, image recognition equipment and high-definition camera equipment, wherein full line image features of the traffic intersection are prestored in the mobile hard disk; the high-definition camera equipment collects images of the traffic intersection to acquire two intersection images at an interval of preset time; the image recognition equipment is connected with the high-definition camera equipment and the mobile hard disk respectively; the two intersection images are processed based on the full line image features respectively; the AT89C51 single chip microcomputer is connected with the image recognition equipment; whether the vehicle crossing the full line and changing the lanes exists at the traffic intersection is determined based on an image processing result. The violation behavior of full line crossing and lane changing of the vehicle at the traffic intersection can be effectively detected, and important reference data are provided for law enforcement of a road traffic control department.

Description

technical field [0001] The invention relates to the field of traffic supervision, in particular to a recognition system for a vehicle merging across a solid line located at a traffic intersection. Background technique [0002] In the prior art, the detection of violations of motor vehicle drivers mainly focuses on two aspects. One aspect is whether to violate the traffic rules corresponding to traffic lights, for example, whether to run a red light, whether to run a green light, and whether to cross the traffic cut-off line. Focus on the detection of illegal behaviors of people inside the vehicle, such as whether to wear seat belts, whether to take children to sit in the co-pilot, etc. However, there is a lack of effective detection measures for the illegal behavior of the driver driving the vehicle across the solid line at the traffic intersection. more dangerous. [0003] In the prior art, the detection of the behavior of vehicles crossing the solid line at the traffic i...
